"host:port" or "[ho:st]:port", depending on whether the host contains colons
like an IPv6 literal. If the host is already bracketed, then additional
brackets will not be added.
Usage is similar to gpr_asprintf: returns the number of bytes written
(excluding the final '\0'), and *out points to a string which must later be
destroyed using gpr_free().
In the unlikely event of an error, returns -1 and sets *out to NULL. */

failure. */
